Steering U-Joint 1in-48 x 3/4in-36

The Steering U-Joint 1in-48 x 3/4in-36 from BORGESON is a precision universal joint engineered to connect steering columns with misaligned shafts, absorbing vibration and accommodating angle changes in custom builds and restored vehicles. This single-joint assembly bridges the gap between 1-inch 48-spline input shafts and 3/4-inch 36-spline output shafts, making it essential for hot rodders, restoration shops, and mechanics tackling non-standard steering geometries where direct shaft connections won't work.

Built from steel in natural finish, this u-joint transmits steering input smoothly while allowing up to 25 degrees of articulation—critical for vehicles with dropped frames, custom dashboards, or repurposed steering boxes. The dual-spline design ensures positive engagement: the 1-inch 48-spline end locks into modern steering shafts found in popular conversion kits and rebuilt columns, while the 3/4-inch 36-spline exit accommodates classic or aftermarket steering boxes. The robust steel construction resists the twisting forces and shock loads inherent in spirited driving, road feedback, and off-center steering loads without premature wear or backlash.

Professionals and enthusiasts benefit most when integrating modern steering columns into classic platforms or when custom-fabricating steering linkage in competition vehicles and off-road builds. Installation requires basic mechanical knowledge—simply match your input and output shaft spline counts to this joint's specifications and secure both ends with retaining hardware appropriate to your application. Verify spline configuration on both your steering column and intermediate shaft before ordering to ensure compatibility.
